Green manures for maize-bean systems in eastern Uganda: Agronomic performance and farmers' perceptions

Autor: Fischler, MA Wortmann, Charles S.

Researchers worked with farmers in eastern Uganda to develop alternatives for soil management using crotalaria (Crotalaria ochroleuca), mucuna (Mucuna pruriens var. utilis), lablab (Dolichos lablab), and canavalia (Canavalia ensiformis) as green manures in short-term fallows. The participatory re...

Nutrient dynamics in a climbing bean and sorghum crop rotation in the Central Africa highlands

Autor: Wortmann, Charles S.

Bean (Phaseolus vulgaris L.) is a major crop in Eastern and Southern Africa, but yields are low. Climbing bean is much more productive than bush bean and is gaining importance with small scale farmers. Our objectives were to: compare nutrient balances with climbing and bush bean in a grain sorghu...

Banana and bean intercropping: factors affecting bean yield and land use efficiency

Autor: Wortmann, Charles S. Sengooba, TNK Kyamanywa, S.

Beans and bananas were grown in sole crop and intercrop systems for three seasons in 1989 and 1990 to determine the effects of cropping system on diseases, insects and land-use efficiency and the roles of certain bean plant physiological traits on bean yield in the two systems. Bean yield in the ...

Haricot bean agroecology in Ethiopia: Definition using agroclimatic and crop growth simulation models

Autor: Simane, B Wortmann, Charles S. Hoogenboom, Gerrit

Bean (Phaseolus vulgaris L.) is an important food and cash crop grown in diverse environmental settings in Ethiopia. Its production is very heterogenous in terms of ecology, cropping system and yield. This study analyses the agroclimatic resources of 18 representative bean growing sites in Ethiop...

Farmer participation in cultivar evaluation: The case of beans

Autor: Ugen, Michael Adrogu Wortmann, Charles S.

Nine advanced bean lines (MCM 5001, CAL 96, RWR 136, AFR 531, AFR 509, UGP 6088, PVA 698, SUG 50 white haricot) were tested on-farm for two seasons of 1992 in Bushenyi, Iganga, Kabale, Luwero, Mbarara, Mpigi, Mubende and Nebbi districts of Uganda. The objective was to evaluate the performance and...
